Abstract (en)

[origin: EP2270088A1] A rubber composition for tires which comprises at least one rubber component selected from natural rubber and synthetic rubbers and, based on 100 parts by mass of the rubber component, 0.1 to 45 parts by mass of (A) a terpene phenol resin and 1 to 150 parts by mass of (B) a softener comprising a process oil which comprises polycyclic aromatic compounds (PCA) in an amount such that the content of extracts with dimethyl sulfoxide (DMSO) in accordance with the method of IP346 is controlled to a value smaller than 3%. A rubber composition for tires which overcomes problems arising due to the use of a highly aromatic oil having a content of polycyclic aromatic compounds (PCA) controlled to a value smaller than 3% as the process oil in place of conventional highly aromatic oils and exhibits excellent loss property and rigidity and a tire which uses the rubber composition and exhibits excellent steering stability on dry road surfaces and excellent braking property on wet road surfaces can be provided.
